Very nice beach, white sand and clear water. You still can swim in the afternoon with low tide. So maybe it's a good idea to spend the morning in Railay West and go after lunch to Phra Nang Beach. Here you can see rock climbing activities, mostly in the morning. Several "tourists" doing the 4-island tour can be seen in life-jackets arriving and departing after a short while. In the morning, almost no sand available to place your towel. As the tide is lower, more sand is available and you can place your towel, either under the trees shadow or under the sun.
